[Q] rooted android but wont update automatically

Hello everyone. Im having an issue where I rooted my phone with the cf auto root kit you guys have graciously provided. Thank u for that. But my phone occasipnally gives me an update alert but wont update cuz its "been modified" and I think its starting to affect my 4g performance or I maybe wrong .. not sure on that one yet. ..but should I update the root or is there a tool I can use..?.. any help would be awesome...

Well it looks like im running NAB. 4.4.2 kit kat and as for the update message I havent gotten for a bit but its a over the air update I believe.

If you want to take the ota your phone must be official under device status..... so more than likely you will need to use Odin to return to stock which you can just use Odin to flash nc5 and you are update now ...
